Problems solved by technology

Many of these cases are difficult to diagnose, and even more difficult to treat.

Because the eye in general (especially the cornea) is not vascularized, systemic drugs do not readily permeate it and are generally not used for therapy of ocular diseases or disorders.

To date, the topical application of antibiotics has been the preferred treatment, however, the results have been limited results.

While cyclosporin A (CsA) has been shown to be effective initially, formulations containing this compound reported significant side effects, including ocular burning, kidney damage and predilection for tumor formation.

This suggests that long term therapeutic use, which is usually necessary in the case of ocular diseases and disorders, may present a risk.

In addition, due to its size and structure, CsA is not water soluble
